    Description

      Attached is:

      • some example data
      • a query that works as I expected, without GROUP BY
      • the same query with GROUP BY and GROUP_CONCAT added, which doesn't work as I expected

      Am I doing something wrong, or is this a bug?

      Using the query without GROUP BY, I get these results as expected:

       

       

      Using the query with GROUP BY and GROUP_CONCAT, I expected to get:

       

      But instead I get:

      thing decimal__Concat boolean__Concat
      <http://example.org/data/a>   <http://example.org/data/a/values/2>
      <http://example.org/data/b>    

       

      Should I be doing something different to get the results I expected?
